+This package provides LLVM/Clang components required by Qt Creator
+in order to extend Qt Creator's functionality. You need to install
+this package prior to compiling Qt Creator to make it work.
+
+Some of the Qt Creator's tools enabled by this package are:
+- Clang Code Model,
+- Clang-Tidy,
+- Clazy,
+- Clang Static Analyzer.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
